Comment on Activity Pub: Can I join a PeerTube or Mastodon server using a Lemmy account?
Pamasich@kbin.earth 1 day agoI think I have to read up on the exact definition of "group".
Represents a formal or informal collective of Actors.
has there ever been discussions regarding SSO?
Don't know about Lemmy specifically, but there has been discussion on SSO in the fediverse in general. There is an FEP (Fediverse Enhancement Proposal) which lists some implementers. I have also heard the client-to-server API part of ActivityPub could be used for this, but I don't think projects usually implement that (it's optional).
It should be theoretically possible to provide SSO for any fediverse project which has an API with authentication. I think. So sign in with Lemmy should be possible, but it's up to those other projects to implement it.

Cheers! Would be cool to see SSO happening as it would simplify joining multiple fediverse instances (PeerTube, Pixelfed, …).
